Filed: 1965-06-29
Abstract: 1,154,032. Welding by pressure; brazing. WELDING INSTITUTE. 27 June, 1966 [29 June, 1965], No. 27561/65. Heading B3R. In welding or brazing two superimposed parts supported on a base of electrically non-conductive material wherein two spaced electrodes are placed on the upper part and current passed through the electrodes and wherein a member of higher thermal conductivity is applied to the upper part between the two electrodes, the two electrodes are spaced apart by a distance not greater than 0À035 inch and the member of high thermal conductivity extends for the major portion of the distance between the electrodes. To join a lead 6, Fig. 1, to an underlying strip 7 on an insulating base 8 an electrode assembly is applied to the lead 6 the assembly comprising three sheets 1, 2, 3 of copper or copper alloy bonded together with two spacing layers 4, 5 of adhesive impregnated tissue, the outer sheets 1, 2 being connected to a battery, alternating current source or a bank of capacitors. The central heat sink 3 may alternatively be of silver, tungsten or molybdenum. The sheets may be rectangular and be held in a holder to present a corner 12, Fig. 2, to the work. The adhesive impregnated dielectric 4, 5 may be replaced by an unbonded film so that the electrodes and heat sink may have relative movement or air gaps may exist between the electrodes and heat sink. A thermocouple or thin film heat sensor or pyrometer may be incorporated in the heat sink so that temperature rise during welding may be employed to indicate or connect weld quality, e.g. the pyrometer may be connected to a circuit which will adjust the energy input for subsequent welds or cause a second current pulse to be applied to the same weld. The voltage or resistance of the workpiece or expansion of the workpiece may be measured. The joining of leads from electronic components to printed circuit boards and to thin films on glass or ceramic substrates is referred to.

Title: Improvements in or relating to the application of adhesive coatings to veneers and other sheet materials
Inventor: TAYLOR JOHN EDWARD
IPC: B27G11/00
Filed: 1963-07-11
Abstract: 1,086,301. Coating apparatus. FACTORIES DIRECTION Ltd. July 6, 1964 [July 11, 1963; April 27, 1964], Nos. 27591/63 and 17466/64. Heading B2L. In applying a layer of adhesive on to sheet material the sheet to be coated is moved relative to a stream of adhesive which falls on to the sheet in the form of a curtain formed by allowing the adhesive to pass substantially horizontally through an elongate orifice which extends transversely to the direction of movement of the sheet and thereafter to fall on to a deflector plate, over the edge of which it falls on to the sheet. In the arrangement shown adhesive trough 2 is mounted horizontally across a table comprising a pair of conveyors 10 on which sheet material to be coated can be traversed, with supports (14) for supporting the sheets as they pass from one conveyor to the other. The trough 2 has an elongated orifice 16 between the lower edge of side wall 15 and the bottom wall 18 and side wall 15 is adjustable at 29 to vary the width of orifice 16. A deflector plate 21 is supported below trough 2 in the path of the stream flowing from the trough so as to prevent said stream from breaking up before it reaches the material to be coated. The trough 2 is kept supplied with fresh adhesive from pipes 22 controlled by valves (23) the adhesive being supplied either from sump (24)which collects adhesive falling through the apparatus, via filters (25), pump (26) and pipe (27) or from a make-up source at (28). A guide element (30) is mounted at each side of the table to prevent the falling adhesive from contracting at the sides. The bottom wall may project a short distance so as to form a shelf over which the adhesive flows and the upper surface of the bottom wall of the trough may slope upwardly towards the gap 16 and for this purpose the bottom wall may be made adjustable to various slopes. Also advantageously the edges over which the adhesive flows on issuing from the orifice and the deflector may be undercut or bevelled and further the deflector plate may be inclined with respect to the direction of the stream.

Title: Improvements in or relating to the concentration of aliphatic acids
IPC: C07C51/48
Filed: 1935-10-07
Abstract: <PICT:0455325/IV/1> In extraction processes for concentrating aliphatic acids from cellulose esterification processes by means of solvents, sludge is removed from the apparatus by admitting the vapour of a solvent or partial solvent and draining away the condensed solvent.  The extraction of acetic acid, for example, may be effected by passing the dilute acid through a column made of or lined with stainless steel, glass, bronze or the like in countercurrent with a solvent such as phenol ethers, ethylene chloride, or mixtures of petroleum ether, kerosene or benzol with ethyl ether, ethyl acetate, chloroform, or acetone oil; and the column may contain Raschig rings or other packing material.  In the apparatus described aqueous acid from 1 is fed to columns 10, 11, 12, any of which may be cut out for cleaning.  Each column has an upper part 13 in which the liquid phases separate, a packed part 14, and a bottom part 15 with sight glasses 16.  The bottom sections of columns 10, 11 are connected by pipes 17, 18 to the acid-feed pipes at the top of columns 11, 12 respectively, and from the bottom section of column 12 is connected to a tank 22, still 23 and dephlegmator 24. Solvent from a tank 25 is supplied to the columns in counter-current to the aqueous acid and the extract is collected in a tank 30 from which it passes by a pipe 34 to a still head 35 from which it may be returned to the tank 25 or preferably is passed through a preheater 36 to a still 38 which has a fractionating column 43.  Concentrated acid is led to a tank 40, and the vapour of the solvent is condensed at 68 and returned to the tank 25.  When a column is to be cleaned, it is cut out of the circuit by the appropriate valves and the liquids are drained away into a tank 50.  Concentrated acid or other solvent for the sludge is vaporized in a still 53 and admitted to the column by way of a pipe 54, the condensate and sludge being received in a tank 63 where much of the sludge separates out, the remainder being led to the tank 51 or to the still 53.  The process may be applied to the extraction of formic, propionic, and butyric acids. The extraction process may be that described in Specification 454,891.  The Specification as open to inspection under Sect. 91 is described generally for the concentration of aliphatic compounds and mentions aqueous acids obtained by distillation or fermentation of fruits or plants or other industrial processes, and aqueous solutions of aliphatic anhydrides.  This subject-matter does not appear in the Specification as accepted.

Title: Preparation of presensitized printing plates
Inventor: GERIS FRANK T
IPC: G03F7/016
Filed: 1969-06-02
Abstract: 1278293 Photo-sensitive materials and printing plates therefrom WISCONSIN ALUMNI RESEARCH FOUNDATION 2 June 1969 27819/69 Headings G2C and G2M [Also in Divisions C4 and C7] A presensitized printing plate comprising a support of Cu, Zn, Al, Fe, Ag, Sn, Pb, Mg, Cr, Mn, Ni, alloys thereof, brass or steel is produced either by (i) abrading the surface of the support while it is wetted with a diazo resin or (ii) abrading the support while wet and then rubbing the wet abraded support with diazo resin solution. In the first method, the support is preferably cleaned to remove dirt and then either wetted with diazo resin solution before abrasion or diazo resin solution is added to the abrasive paste e.g. rose tripoli, silica glass powder or pumice. An anti-oxidant such as thiourea or hydroquinone may be added to the diazo resin solution or the process carried out in an inert atmosphere to prevent oxidation. The plate produced may be used as a photo-lithographic plate or be further coated with a solution of diazo resin which may be water-soluble (A-stage) preferably coated in an inert atmosphere or in the presence of an anti-oxidant or partially cross-linked (B- stage) if coated in the presence of oxygen. The further coated plate may be imagewise exposedand electrolytically etched which etches the metal in the areas underlying the unexposed areas with the A-stage resin and the metal underlying the exposed areas with the B-stage resin. However, rapid etching of a magnesium support occurs under the unexposed areas irrespective of resin used. The plate may now be developed to remove all the diazo resin and used as a gravure printing plate or etching may be continued until areas of A-stage resin above etch is removed and then the remaining unexposed areas exposed to produce an oleophilic surface and thus produce a lithographic plate. The wells of the gravure plate may be strengthened and made more oleophilic by plating with copper. In the second method, the metal support is scoured with a rose tripoli or white tripoli paste, washed with acid and then water and whilst still wet coated by rubbing with diazo resin solution. This rubbing may be produced by (a) vigorous scrubbing with a squeegee or (b) repeatedly passing the plate between compressed rotating rubber rollers. A- or B- stage diazo resins may be used; the B-stage resin may be produced by heating, after coating. Alternatively, after imagewise exposure, the resin may be hardened by heating or treatment with cupric bromide and a ferrocyanide before electrolytic etching as above to produce a gravure plate.

Title: Improvements in or relating to the manufacture of coating and impregnating compositions
IPC: D06M15/09
Filed: 1934-09-29
Abstract: Cellulosic materials such as cotton, wood pulps, bast fibres, jute, sisal, flax, and hemp are coated or impregnated with solutions of cellulose derivatives in solutions of halides or thiocyanates of metals belonging to Groups 2 or 3 of the Periodic Classification. The metal salts may be in solution in water, aqueous alcohol, or lower aliphatic acids or their anhydrides. In an example, acetone-soluble cellulose acetate is dispersed in a solution of zinc chloride in water and methylated spirit, the cellulosic material is immersed for a few seconds, removed, heated and washed with water. In another example jute fabric is immersed at 70--75 DEG  C., in a solution of cellulose triacetate in zinc chloride, glacial acetic acid, acetic anhydride and benzene, and is removed, squeezed, washed, and dried on hot calenders.  The material is water resistant and immune to the attack of bacteria. In a third example, fabric is steeped in a bath containing a solution of zinc chloride and is then passed into a solution consisting of cellulose triacetate dispersed in a solution of zinc chloride, glacial acetic acid, acetic anhydride and benzene at 50--60 DEG  C.  The fabric is removed, washed, and dried under tension, and may then be treated with a solution of a plasticizer for cellulose acetate, e.g., a solution of triacetin, methyl phthalate, and tricresyl phosphate in methylated spirit.
